Abstract: An investigation entitled “Effect of soil application of Fe and Zn on nutrient content and uptake by two rice varieties” was carried out during kharif, 2014 at Department of Natural Resources Management, ASPEE College of Horticulture and Forestry, Navsari Agricultural University, Navsari. The present pot trial consisting of 20 treatment combinations involving two varieties (V1: GNR-4, V2: IET-23833) and ten micronutrient levels (M0:- Control, M1:- 2.50 mg Fe kg-1, M2:- 5.00 mg Fe kg+, M3:- 7.50 mg Fe kg-1, M4:- 10.00 mg Fe kg-1, M5:- 1.25 mg Zn kg-1, M6:- 2.50 mg Zn kg-1, M7:- 3.75 mg Zn kg-1, M8:- 5.00 mg Zn kg-1, M9:- Grade 5 @ 12.0 mg kg-1) was conducted in FCRD with three repetitions. The experimental results revealed that variety V2 recorded significantly higher content of Ca (0.211%), Fe (136.5 mg kg-1), Mn (22.5 mg kg-1) and Zn (78.2 mg kg-1) in grains as compared to variety V1 with an exception of P (0.18%) which was significantly higher in V1. In case of straw portion also, significantly more content of P, Ca, Zn and Cu was recorded in variety V2 than V1, but it was not true for Mg, Fe and Mn content. As far as micronutrient levels are concerned, application of either Fe (M1 to M4) or Zn (M5 to M8) significantly increased the N, P, Fe and Zn content in all parts (grain, straw and root) of rice as compared to control. With respect to nutrient uptake, significantly higher uptake of N, P, K, Ca, Mg, Fe, Mn and Cu by grain and straw was registered in variety V1, while variety V2 registered significantly higher uptake of Zn by both grain and straw of rice. Further, most of the treatments receiving Fe and Zn, removed significantly higher amount of all the determined nutrients from soil, as indicated in higher content in grain and straw of rice as compared to control.
